Aleja Productions (which staged a bang-up rendering “The Last Five Years” in January under the name UnderMotion) opens “True West” this weekend. Sam Shepard's dark comedy is about brothers (Thomas Sorensen, left, and company founder Alex Trevino) who bring out the worst in each other. At the first read-through, director Phil Cerroni told cast and crew that he saw the piece as “a romance between the two brothers — a violent romance between two people who are trying to connect with each other but can't.” Ben Scharff and Twyla LaMont round out the cast.
